What were the consequences of the Mexican-American War for the United States?

• A. Acquisition of California and New Mexico; debates over slavery in new lands
• B. Ended slavery in new territories
• C. Created the Florida Territory
• D. Initiated the Texas Revolution

Answer: (A)

Territorial expansion and the way a nation handles politics in new lands are what this question is getting at. After the Mexican-American War, the United States gained a large swath of territory through the Treaty of Guadalupe Hidalgo, including California and much of the Southwest (areas that would become California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming). This dramatic land gain expanded the country’s geographic reach and economic potential, but it also raised a fierce question: would slavery be allowed in these new territories and states? The debate over extending or restricting slavery into these lands intensified sectional tensions between free and slave states and helped shape national politics in the 1840s and 1850s, influencing compromises and party realignments. The other choices don’t fit because the war did not end slavery in new territories, did not create the Florida Territory, and did not initiate the Texas Revolution.
